Kamlakant Patel f002612b9d ipmi_ssif: Fix kernel panic at msg_done_handler 
This happens when BMC doesn't return any data and the code is trying
to print the value of data[2].

Getting following crash:
[  484.728410] Unable to handle kernel NULL pointer dereference at virtual address 00000002
[  484.736496] pgd = ffff0000094a2000

Adding a check to validate the data len before printing data[2] to fix this issue.
